Embodiment 1

[0031] like figure 1 and figure 2 As shown, this embodiment provides a sulfur autotrophic denitrification denitrification reactor, including a reactor body 3 and a swirling water distributor 2 located at the bottom of the reactor body 3 . Among them, the swirl water distributor 2 includes a water inlet 18 and a plurality of water distribution channels 17 uniformly distributed around the water inlet 18, and the two side walls of each water distribution channel 17 are arc-shaped from the connection with the water inlet 18. The end extends away from the water inlet 18. Therefore, the sewage entering the main body of the reactor through the water inlet can generate hydrocyclone after passing through the arc-shaped water distribution channel. The mixing is more thorough, avoiding the formation of a hydraulic dead zone at the bottom of the reactor body.

[0032] Preferably, the reactor body 3 is cylindrical. The inner diameter of the reactor body is R.

Abstract

The invention provides a sulfur autotrophic denitrification nitrogen removal reactor and a sewage treatment system, relates to the technical field of sewage treatment equipment, and solves the technical problem of low mass transfer efficiency caused by influence of non-uniform water distribution in a sulfur autotrophic denitrification nitrogen removal reactor in the prior art on fluidization of carrier particles. The device comprises a reactor main body and a rotational flow water distributor located at the bottom of the reactor main body, the rotational flow water distributor comprises a water inlet and a plurality of water distribution runners uniformly distributed in the circumferential direction of the water inlet, and the two side walls of each water distribution runner are arc-shaped and extend outwards from the end communicated with the water inlet. According to the reactor disclosed by the invention, sewage entering a reactor main body through the water inlet can generate hydraulic cyclone after passing through the water distribution runners, the arc-shaped water distribution runners enable water flow to generate vortex more easily, the vortex flow enables the sewage and a denitrification carrier to be mixed more fully, a hydraulic dead zone is prevented from being formed at the bottom of the reactor main body, and energy consumption is saved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sulfur autotrophic denitrification denitrification reactor and a sewage treatment system, which are used in the sewage treatment industry to denitrify sewage. Background technique [0002] At present, the commonly used denitrification process in the field of sewage treatment is heterotrophic denitrification. Heterotrophic denitrification uses organic matter as a nutrient source to completely reduce nitrate to nitrogen through metabolism. The heterotrophic denitrification process has a fast reaction rate and stable system operation, but the value-added of sludge is relatively rapid, and due to the common problem of insufficient carbon sources in urban sewage in my country, it is often necessary to add methanol, sodium acetate or glucose to the water when using this process As the organic carbon source of heterotrophic denitrifying bacteria, it leads to the dis...
